A practical and efficient method to synthesize thiocarbamyl fluorides and isothiocyanates from amines with trifluoromethanesulfonyl chloride was developed. In the presence of the reducing agent triphenylphosphine and sodium iodide, thiocarbamyl fluorides and isothiocyanates were synthesized from secondary/primary amine in moderate to excellent yields, respectively. A broad scope of substrates and good functional group compatibility were observed.

A microwave-assisted desulfuration of readily available dithiocarbamates, formed in situ from primary amines, leading to target isothiocyanates has been developed. This efficient protocol provides a rapid, environmentally benign route to aliphatic and aromatic isothiocyanates.

Paragraph 0014; 0018, (2019/05/22)
The invention discloses a method for jointly preparing isothiocyanate and phosphorus, nitrogen and sulfur flame retardants. The method comprises the following steps: taking amine and CS2 as raw materials; generating dithiocarbamate by reacting in a solvent under the existence of alkali; reacting with neopentyl glycol phosphoryl chloride, thereby acquiring an isothiocyanate compound (I); acidizingby-product 1,3,2-phosphorus dioxidehexane thiophosphate (II); generating a salt by reacting with melamine in the solvent, thereby acquiring the phosphorus, nitrogen and sulfur flame retardants (III).According to the method provided by the invention, isothiocyanate and phosphorus, nitrogen and sulfur flame retardants can be jointly prepared; operation is simple and convenient; product yield is high; atom is economical; the prepared phosphorus, nitrogen and sulfur flame retardants (III) have an excellent anti-flaming effect.
